Review: Great stability and comfort - This knee brace is top notch! I recently had some knee issues and purchased this brace to wear on a long trip and through airport security -it was easy peasy! This brace provides the best stability and comfort. It’s easy on and off with wide velcro straps. I dont think my trip would’ve been as smooth as it was without this brace. Only wish is that I would’ve sized up because my knee was very swollen and could’ve used a little extra room. Overall, I would definitely purchase this brand again.
Review: Very well made - A friend of mine that is a physical therapist recommended to get a Don Joy brace. I got this one. One on it is comfortable and very firm. It is about twice the thickness of a similar brace I purchased a while ago. I think the extra thickness contributes to the firmness and stability as well the comfort. I would easily get another one. My only positive that isn't positive is that it's a bit of pain to get on compared to other braces. I feel like I need another hand or someone else to do it. It is mostly the nature of the brace, but a bit the location of the velcro. But once it is one it is very comfortable and seems to protect the knee.

### ⭐⭐⭐⭐ Not bad, but could be better
*by J***E on July 31, 2021*

If you are looking for a general knee brace for minor injuries and are not 100% sure what to get, this is one of the better options on Amazon. It is a much better quality than any of the cheaper quality “performance braces” and it’s a good value for the money spent. I tore my PCL 15 years ago, elected not to do surgery at the time (I was about 20), but now experience medial patella luxation. I bought this to replace my favorite performance brace until I can get a custom one, so I really didn’t want to spend over $100 while I wait to be fitted for my custom brace. Pros: 1) Not bulky, light weight, fairly comfortable. 2) I am able to run and maneuver flawlessly at high speeds without being held back by this knee brace. 3) I feel pretty stable while running on uneven surfaces without pain caused by the brace. 4) The hinges so far move smoothly - I beat my braces up and train on dirt surfaces. Cons: 1) The placement of the velcro for the wrap aspect of this brace is definitely awkward, making it difficult to put on especially if you plan to use it for your left knee. 2) Most knee brace sizing says that if you are borderline for their sizing guide - size up. This is not the case with this brace. I sized up and have regretted that decision. 3) For some reason they have added a “stash pocket” which they thought was a cool idea, but just seems silly and awkward in my opinion. Overall: not a bad brace for the money, but definitely not ideal for me.
